Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).
Answer:
Arteries
Explanation:
There are three main types of blood vessels: veins, arteries, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body parts. Veins pick the deoxygenated blood and deliver it to the heart to be oxygenated.
Arteries are the blood vessels with thick walls and no valves. Blood is pumped with higher pressure from the heart into arteries. The pulmonary artery is the only exception that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
<h2>Answer is option "A"</h2>
Explanation:
- Rehashed utilization of a similar class of pesticides to control a bug can cause unwanted changes in the genetic stock of a vermin prompting another type of counterfeit determination, pesticide opposition. At the point when a pesticide is first utilized, a little extent of the bug populace may endure introduction to the material because of their unmistakable hereditary cosmetics
- These people go along the qualities for protection from the people to come. Resulting employments of the pesticide increment the extent of less-helpless people in the populace. Through this procedure of choice, the populace step by step creates protection from the pesticide. Around the world, in excess of 500 types of bugs, bugs, and arachnids have built up some degree of pesticide opposition
- Hence, the right answer is option "A"
Answer:
Decreased biodiversity
